This morning we noticed Newegg.com posted up their Windows 8 listings with upgrade versions as well as full OEM versions. The upgrades are priced at $69, which will allow you to seamlessly upgrade your Windows XP, Vista, or 7 PC straight to Windows 8. They offer a version with the disc and all, or you can go for the product key-only, both will cost you $69 each.

Newegg also has Windows 8 and Windows 8 Professional up on their site, both are available in 32-bit or 64-bit flavors. The regular Windows 8 variant will cost $99 for either the 32-bit or 64-bit version, and Windows 8 Professional will cost $139 for either 32-bit or 64-bit. The prices are comparable to past Windows operating systems. However, Newegg is offering a $10 pre-order discount if you buy the OS before it launches.

We decided to peek over to Amazon to see if they had Windows 8 up for pre-order, and indeed they did, but we could only find the Windows 8 Pro upgrade version. We're not sure when they'll list the rest, but it should be soon considering Newegg is already up and going.
